Oh thanks this was very helpful! I just went and tried running `guix build --no-grafts -d` and it behaved as I expected it to before, returning only the derivation path without building it. I hadn't used `--no-grafts` previously, and that seems to be the crucial difference for this workflow; `guix build -d` without `--no-grafts` seems to attempt a build of (some/all of?) the packages in the derivation.
